Samba's winbind and SELinux conflict
by Filipe Brandenburger 10 Jan '08

10 Jan '08

Hi, I was trying to setup winbind on a CentOS 4 host to authenticate to the AD on my network. My smb.conf is very simple, I'm only setting workgroup, realm, security, and I'm setting for winbind: encrypt passwords = yes winbind separator = + idmap uid = 10000-20000 idmap gid = 10000-20000 When trying to start the service with "service winbind start", I'm getting these error messages: Jan 10 16:18:00 myhost kernel: audit(1199999880.483:2): avc: denied { write } for pid=4490 comm="winbindd" name="secrets.tdb" dev=sda2 ino=192690 scontext=root:system_r:winbind_t tcontext=root:object_r:samba_etc_t tclass=file Jan 10 16:18:00 myhost winbindd[4490]: [2008/01/10 16:18:00, 0] passdb/secrets.c:secrets_init(67) Jan 10 16:18:00 myhost winbindd[4490]: Failed to open /etc/samba/secrets.tdb Jan 10 16:18:00 myhost winbindd[4490]: [2008/01/10 16:18:00, 0] nsswitch/winbindd.c:main(1010) Jan 10 16:18:00 myhost winbindd[4490]: Could not initialize domain trust account secrets. Giving up Clearly winbind is violating SELinux's targeted policy by trying to write the secrets.tdb file on /etc/samba directory. I looked at smb.conf's man page that I could set the directory of this file using the "private dir" directive on smb.conf's global section, and that's what I did, I set it to /var/cache/samba/winbindd_privileged, which I found was a directory created by the samba-common package, with 750 permissions and a winbind_var_run_t context. I would like to know if I did the right thing or not. Or if I should have put the secrets.tdb in a directory other than that one. What would be the recommended configuration? Thanks! Filipe

Hi, Has someone created RPM packages of citadel for CentOS 4 or 5? I would be interested. If anyone has it in a public repository and would like to share, please tell me. I looked for it in CentOS base repositories and Rpmforge but didn't find anything. Anyway, please let me know. Thanks! Filipe

NFS problems with CentOS 4.5
by Mark Belanger 10 Jan '08

10 Jan '08

Our large and complex build system is having very sporadic failurs as we try to update to CentOS 4.5. This takes the form of files that exist - and have existed for some time - not being found: file.whatever: No such file: No such file or directory This happens both with source files, .o's - meaning that the errors come from both the compiler and linker. The build storage is on NFS and the errors don't happen when we target local disk. We also have solaris nad Centos 3.x building the same code base in a similar fashion with no problem. We are currently using mount options of: rw,nosuid,bg,timeo=50,retry=1 And have also tried: rw,intr,bg,proto=tcp,nfsvers=3,rsize=32768,wsize=32768 without success. Any suggestions welcome. -Mark

Remove the __db* files and then "rpm --rebuilddb" is usually sufficient unless you have non-standard locations for the database. Cheers, Dave -- Politics, n.

Probably OT: Has anyone else seen SeaMonkey 'pop' without warning?
by MHR 10 Jan '08

10 Jan '08

I sent a bug report to Mozilla about this, but I was hoping someone here might have an insight on this. I use SeaMonkey as my default browser (32-bit even though I'm running x86_64 CentOS 5.1), version 1.1.7. Shortyl after installing 1.1.7 on my 5.0 (and even since 5.1), I noticed that every so often, seemingly at random, although it appears most frequently when I click on something that wants to interact with the file system, the SeaMonkey window just closes. If I reopen it and go to the same place and try the same thing, it works just fine (and usually, the second SM window is more stable and doesn't do that again). This frequently happens when I try to save a web page, load an email attachment, print a page, or anything that interacts with the file system. Just now it happened when I tried to switch tabs, but that's unusual. Anyone have a clue? TIA. mhr

CentOS 5 & sendmail configuration
by Frank M. Ramaekers 10 Jan '08

10 Jan '08

I'm attempting to configure sendmail to relay outgoing mail to an internal smtp server. I found that the commented line in sendfile.mc that starts with 'dnl define(`SMART_HOST'... needed to be uncommented and a valid value inserted. No problem there, but when I attempt to 'make -C /etc/mail', I get WARNING: 'sendmail.mc' is modified. Please install package sendmail-cf to update your configuration. make: Leaving directory `/etc/mail' Researching further, it seems I need to install the 'sendmail-cf' package, which I can't seem to find with yum. What piece of this puzzle am I missing? TIA, Frank M. Ramaekers Jr. Systems Programmer MCP, MCP+I, MCSE & RHCE American Income Life Insurance Co.
